Deltarune's World

Kris's Appearance: Kris is a human male teenager with an tangerine yellow. skin tone and messy, shoulder-length dark maroon hair. He wear a long-sleeve lime shirt with one horizontal yellow stripe, and nondescript pants and shoes. One of Kris's distinct traits is that his long bangs cast a shadow that hides the upper half of his face. In the brief moments his tear the SOUL out of his body, his red eyes can glow in the dark. One of his crimson eyes is also visible for a few frames when he descend into a Dark World.

In a Dark World, Kris's entire appearance transforms, making them resemble a knight. Kris dons silver armor: shoulder pauldrons, a cuirass, gauntlets, and boots. He wear a navy blue bodysuit underneath the set, and a pink cape drapes across his right shoulder. Finally, Kris's skin changes to cyan, and his hair transits to navy. The shading for his skin is also used for hia cape, giving the illusion of blue stripes.

To the player, Kris consistently has a blank, neutral expression. They seemingly stand straight during the majority of non-scripted actions. Kris's expressions and movement are different when they are about to removed they SOUL (Player) when alone.

Kris's Pesonality: During the events of Deltarune, Kris is mentioned to be introverted. Both Susie and King refer to Kris as a "quiet person," and Noelle is astonished if they want to talk about "anything." After Kris's brother, Asriel, left for college, they became distant from their few friends. Kris's side of their shared bedroom is also strikingly bare. The shared game console is underneath Asriel's bed, their old children's books are in Toriel's classroom instead, and they have no trophies on their shelves. Toriel also mentions that Kris is not normally energetic. They have a history of not waking up on time, and often sleep through the start of class. Kris also prefers someone else getting them to and from school.

Contrary to Kris's apparent detachment, they do have a variety of interests. Kris has always been mischievous, frequently pulling pranks on Noelle such as hiding under her bed to scare her. Kris also attempted to flush a bath bomb down the toilet at their home at one point, and Toriel is weary that they will try it again. When they were younger, Kris studied the occult with Catti. They appear to still have an interest in the topic, as one of their search queries was "how to use magic." Kris likes video games, having frequently played games with Asriel in their childhood, and they can seemingly defeat Berdly in competitive games. They have also searched for tutorials on how to play video game songs on the piano.

Kris enjoys playing the piano. Prior to the game, they frequently played the hospital piano, and the receptionist believes they can play "beautifully." In a private post from Noelle's blog, Noelle mentions that Kris would often come to her house and use her family's piano since Kris did not have one in their home. Noelle explains that whenever she followed them into the dining room to listen, Kris would immediately stop playing. Without an interruption from Noelle however, Kris would continue playing, sometimes for hours at a time. If the player makes the SOUL wait in the kitchen of the Holiday residence after Kris closes the vent, Kris can be heard playing piano renditions of the Deltarune soundtrack. Kris seems upset by the player's inability to play the piano, as they look angry when Susie laughs at their bad playing while under the player's control, and actively tries to prevent saying that they'll never play again.

Kris's favorite food is Toriel's pie, though they seem to like sweet and especially chocolatey foods in general. They always take a piece from the Box of Heart Candy, like hot chocolate and are implied to really like Choco Diamonds, as it heals them more than any other party member.

Kris is shown to have a significant amount of agency outside of the player's choices. This is most clearly shown in scenes where Kris rips the SOUL out of their body, usually trapping it in a confined space to prevent being followed. They are also able to influence some dialogue choices, occasionally, the player may choose an option that other characters note sounds like Kris is straining to say or that Kris outright refuses to say out loud. Kris is also shown performing actions independently of the player's control, including protecting Susie from King or drinking juice with her in church, showing their friendships exist outside of the player's influence. Additionally, there are instances where Kris stops inspecting something to prevent the player from learning more: when inspecting Asriel's room in Queen's Mansion, Kris closes their eyes before seeing anything; when inspecting an article about Asgore's removal from the police force, Kris intentionally stops reading before the reason is given; and when turning the doorknob in the church, they refuse to open the door. At the end of Chapter 1, Red Big Mouth and Toriel both comment on Kris's physical appearance. They claim that Kris seems "a little sick" and does not "look quite [themselves]" respectively. This implies that being under the SOUL's control slightly changes how healthy Kris looks, and is outright confirmed to change their voice and behavior, which Noelle comments on.

The separation between the player and Kris is most clearly shown in the Weird Route, where it is heavily implied Kris's actions are being done by the player against their will. Noelle describes the voice she heard giving her orders as terrifying, noting Kris has been acting very strange lately. When Kris reunites with the party after defeating Berdly, Susie and Ralsei immediately notice Kris appears distraught. In Chapter 4, Kris gives the player multiple choices to abort the route which are directed at them specifically and punishes the SOUL in a violent outburst if the route is continued. Kris also tries to remedy the player's actions by comforting Noelle and bringing Berdly to the hospital, likely at a time when the SOUL was still in the birdcage.

Kris is noticeably distraught after defeating Spamton NEO in the normal route, and Susie notices Kris appearing to be in shock. If the player responds to Susie question if they're okay by saying Yes, Kris appears strained in their response, making Susie think that they're not okay; if the player responds by saying No, Kris yells out the response, concerning Susie and Ralsei. This heavily implies that Spamton's dialogue about being a puppet and cutting his strings to be free, combined with Spamton's ultimate fate, deeply unsettled Kris.

Susie's Appearance: Susie appears to be a tall, purple, vaguely reptilian monster with messy aubergine hair and clawed hands. She has large eyes with yellow scleras, freckles at the sides of her face, and yellow fangs. Her attire consists of a long purple cardigan, a light blue trimmed white shirt, a pair of torn jeans and a pair of black shoes.

In a Dark World, Susie's skin and hair colors transits to lavender pink and plum respectively, although Darkners still refer to her as purple. Her clothes are replaced with a long black vest with purple trims, a sleeveless purple shirt, baggy plum pants, and black boots with golden soles. She also has two black bracelets with yellow spikes on each arm, and a black belt with a large golden heart buckle.

it is implied Susie has a short tail that wags when she is happy, though she is embarrassed by it.

During most of Chapter 1, Susie's eyes are hidden behind her hair, outside of certain sprites and facial expressions. After she is grazed by King's attack on the rooftop of Card Castle, her yellow eyes are uncovered and often kept visible.

Susie's Pesonality: Susie is often rude, vulgar, and swears frequently. She is prone to being sarcastic, can make brutally honest remarks, and is quick to insult. At times, Susie threatens with physical violence, though this is occasionally as a joke. In a Dark World, Susie generally has no qualms with FIGHTing Darkners.

However, Susie has a different temperament to those who are kind to her. With friends, Susie is expressive, willing to talk about herself, and ask for their opinions. Susie favors teasing her friends and enjoys spending time with them. She is observant of their emotions, and tries to be considerate and not inquire about stressful topics. Susie is also loyal, readily wanting to assist a friend if they are in danger or troubled.

She likes compliments, and is easily flattered. Susie also enjoys causing mischief and childish antics, such as trying to fit in a freezer. She appears to like eating in general, including non-food items, and receiving gifts. She is possessive of items given to her.

Susie is implied to have self-esteem issues. She appears convinced that no one likes her, and is oblivious to Noelle's crush on her. She is also aware that she struggles academically. Susie can also occasionally project onto others. After she learns that Tenna feels abandoned and alone, she reveals that she never had any real friends prior to her adventures, and she believed she would never make any in Hometown.

After meeting Gerson Boom, Susie begins to grow more confident in herself, and begins to embrace her role as the hero from the prophecy. While she feels that her healing magic is inadequate compared to Ralsei, he goads her into using it anyway, helping her to realize its potential. She later states that he is the first person she is genuinely learned from, showing an increase in confidence. Even after learning of the prophecy's tragic ending, Susie remains defiant, adamantly claiming that she will not let it happen.

She seems to fall asleep easily, as evidenced by the use of the Sing command in the battle against her and Lancer, and at the end of Chapter 2, where she falls asleep almost immediately after she and Kris sit down and start watching television. Susie eats almost anything, as seen when viewing the refrigerator in her Castle Town room. She is very particular about any actions with her equipment in the equip menu, such as refusing to wear any ribbon armor or refusing to re-equip the Mane Ax after it has been taken off.

Ralsei's Appearance: Ralsei is depicted as a short Darkner he wears round green glasses, a pink scarf, and a long, green cloak with a black heart in the center. Ralsei face resembles a similar face to Asriel's Undertale counterpart, with the exception of glasses, pink shaded horns, and pink fur accents. Without his glasses, his eyes are visibly pink-colored with detailed eyelashes and what appears to be pink eyeshadow.

certain details of Ralsei's robe change compared to his Chapter 1 appearance. The sleeves on Ralsei's robe change to black, the edges become more uniform rather than appearing tattered, and the emblem on his chest appears to change from a heart to an inverted spade. The latter matches early concept art by Temmie Chang. This element is only present on some of his sprites, with most of his in-battle sprites and some of his overworld sprites reverting to a heart emblem.

When downed in battle, Ralsei disappears, leaving only his clothes on the ground.

Ralsei's Pesonality: Ralsei is very humble and kind, showing genuine care for the well-being of his friends to the point of selflessness. At the beginning of Chapter 1, Ralsei tries his best to befriend Kris and Susie in order to fulfill the Prophecy with them. Trying to be on good terms, he shows reluctance at getting angry and appears disappointed when Kris or Susie act mean. Nevertheless, Ralsei remains convinced that they have good in them and that fighting is not necessary in this world. His naivety almost costs him his life when he accepts King's fake-out surrender and heals him, allowing him to betray and defeat them. Ralsei learns from this to not always be so trustful of others.

Ralsei enjoys baking cakes, especially for his friends. This caring side sometimes shows up when he encourages Susie and Kris to do their homework, emphasizing the importance of education, indicating his responsible nature. Despite his occasionally bossy behavior, he is himself prone to being the one bossed around, especially by Susie. He becomes flustered when receiving gifts or affection, likely due to his past isolation and lack of familiarity with others.

Although gentle and shy, Ralsei is equally courageous, as he seldom retreats in the face of danger and displays no fear in life-threatening situations.

Though hints of this appear earlier, Chapter 3 and 4 heavily emphasize his need to be useful to Kris and Susie, as well as his generally low self-worth. He expects to be abandoned by Kris and Susie when they manage to make friends in the Light World and thinks his sadness over the prospect is selfish. He also encourages fellow Darkners to prioritize the feelings of Lightners over their own. Both Kris and Susie have moments where they reassure his feelings and promise to stay his friend.

Ralsei also differs from other Darkners in that he is able to survive in any Dark World without turning to stone. He is also aware of the connection between a Dark World and the Light World, as he knows about the unused classroom and its connection to the Card Kingdom.

Ralsei appears to use British or Australian English, using words such as "lift" to refer to an elevator, "bum" instead of ass, and "fancy" or "chuffed" to refer to liking something.

Noelle's Appearance: Noelle is a reindeer-like monster with short brown fur, a red nose, freckled cheeks, and prominent front teeth, as well as a pair of small antlers atop her head. She walks upright, and has long golden blonde hair. She wears a red and green checkered sweater with dark grey sleeves and a dark grey skirt. Noelle's nose being red is likely a reference to Rudolph the Red-Nosed Reindeer, while her red and green sweater is likely due to these colors being associated with Christmas.

In the Dark World, her hair becomes pale blonde and her fur obtains a pinkish tone. She also wears a long white dress/robe with a hood and ample sleeves but her smile turns into a straight face/frown.

Noelle's Pesonality: Noelle is friendly and cheerful, but also very timid, and sometimes has trouble saying what she's thinking. She apologizes often, and stays quiet about her feelings, such as her crush on Susie or her frustration with Berdly, out of fear. Her father says that "everything scares her," and describes her as "defenseless." According to him, she has a fear of humans hiding under her bed. This was made worse (or started) by Kris's repeated attempts to scare her when they were younger, including at least one time they hid under her bed. She shows to be more honest to Kris when it comes to her feelings and often yells at them when they pull pranks on her. She becomes more brave and less fearful from Chapter 2, during the time she spends with Kris in the city.

Noelle apparently has tendencies of masochism, particularly fantasizing about Susie bullying her for various things (e.g. Susie pushing her over and laughing at Noelle for asking Susie to ride with her on the Ferris Wheel), and stating that the Ragger "feels nice" when attempting to equip it on her. She feels nostalgic thinking of times she was scared in the past, and didn't mind being scared because it meant someone would comfort her. Noelle appears to dislike meat and enjoy eating vegetables, as shown by her reaction to eating Darkburger and Giga Salad, respectively. This could be due to the fact that real-life reindeers are herbivores.

However, Noelle does have brash moments that push aside her shy behavior. An example of this was when Berdly admits that he may have feelings for Susie, which causes Noelle to angrily shake him since she has a crush on Susie as well. She also fantasizes about grabbing and shaking him after he asks her on a date to the festival. She also eventually stands up to Queen at the end of Chapter 2 instead of making a Dark Fountain for her.

Berdly's Appearance: Berdly resembles a large avian with blue feathers, a yellow beak, and yellow legs. He wears black framed glasses, a collared white button-up shirt with striped sleeves, and a black shirt layered underneath.

In the Dark World, Berdly's feathers are a lighter shade of blue, and the whites of his eyes are bright green. He wears a "Smart Scouter" on his head that consists of an orange tinted lens and two white and green pointed headsets. His ensemble consists of an orange cape, futuristic white armor with pointed shoulder guards, bracers and leg armor. He wears a black bodysuit underneath this armor, and has green cloth wrapped around his waist. In battle, Berdly uses a green laser halberd with a yellow ax blade and yellow eyes embedded into the blade's head.

Berdly's Personality: Berdly is sarcastic, arrogant, projects great self-esteem, and considers himself one of the smartest students of his class. He is shown to be very disdainful of his fellow classmates (especially Susie), but has respect for Noelle, whom he considers the actual smartest student. Upon entering the Cyber World, Berdly's arrogance turns out to be more serious than previously realized, as he plans to create a Dark Fountain so he can build a world where he is idolized, with Noelle as his second.

Berdly is very unaware of how others perceive him. For instance, he is oblivious to Noelle's contempt and thinks she is in love with him and also fails to understand that Queen views him as her minion rather than an ally.

Despite his arrogant and annoying disposition, Berdly is shown to not be as clever as he says he is, as demonstrated by his inability to solve puzzles. He eventually confesses that he never really thought he was as intelligent as he claimed, and that he was only able to get good grades because Noelle helped him with his homework. His insecurities begin to eat him alive to a point where he feels everyone's expectations of him are so high, he can't imagine how it feels if he can't live up to them, or even what happens if he can't get along without Noelle's, or anyone else's, help. After Susie reassures him that he doesn't need to be smart, Berdly decides he wants to be an idiot instead, much to her annoyance. Once he wakes up from his "dream" in Dark World (though still unsure whether or not what he experienced was a dream), his opinion of Kris and Susie begins to soften somewhat, even going so far as to develop a crush on Susie and view her as some form of role model.

Berdly is also a huge video game fanatic and seeks a partner who shares this interest. He does, however, despise mobile video games.

During the Snowgrave Route, upon meeting Berdly after the Annoying Mouse Puzzle Room 3, Berdly shows capacity to understand the situation Noelle is in, and that he cares about her enough and is brave enough to fight the party and attempt to free her from Kris's wrongdoings, unbeknownst to him that they are under the player's influence on this route.

Toriel's Appearance: Toriel shares a similar appearance as her Undertale counterpart, though she has a small tuft of fur on the top of her head, and does not wear her distinct Delta Rune tabard. Instead, she favors casual clothes, which consists of an iris long-sleeve jacket, a black blouse, and a polka-dot skirt. She also wears a heart pendant and color matching glasses, though the former is not visible on her overworld sprite, and the latter cannot be seen on her dialogue sprite.

Toriel's Personality: Toriel has a kind and motherly temperament, as she is a parent to Asriel and Kris; and is a teacher for the younger students at the local school. She is tidy and old-fashioned, as her house has a landline telephone, as well as a television with an external antenna; her interests include baking, teaching, reading, snails, and puns. Toriel is religious and keeps a book of hymns in her home.

Toriel is also prone to being judgmental. She appears to expect trouble from Kris since she recalls their past mischief, such as the time they put a bath bomb in the toilet, and emphasizes that Kris should not consume all the pie. Her judgmental nature extends to her severed relationship with Asgore. While she refrains from criticizing Asgore directly in front of Kris and allows them to freely visit him, she lets her disdainful feelings toward him show on her face, and rebuffs his attempts at reconciliation.

Asgore's Appearance: Asgore is a large and tall white-furred monster with a goat-like appearance. Asgore has two large curved horns, golden-blond mane, golden-blond full beard, white fur, long ears, a snout, and a set of visible fangs. His talksprite depicts him as having a slightly-split mustache at the center, unlike his overworld sprite. Asgore has broad shoulders and muscular arms, with his forearms having long strands of gold arm hair. He appears to have a more rotund stomach, and has bulky legs and three-toed feet.

Asgore wears a Hawaiian T-shirt, which is pink and has varying white flowers patterned on it, and a simple pair of blue jeans.

Asgore's Personality: Asgore is affectionate and eager to please, but can overstep boundaries and can act somewhat thoughtlessly. This includes when Asgore cooked the eggs he painted for one of Asriel's birthday parties. He dwells on his past relationship with Toriel, and tries to reconnect with her and his children whenever he has the chance. Despite this, Asgore tries his best to not be emotionally overwhelmed by tending to the flowers.

Asgore is attentive in his interests. This includes flowers that are difficult to care for. Asgore has a tendency to selflessly give flowers away to people for free. This includes Toriel, Rudy, and Alphys. Due to this, he owes rent to "C," which he is unable to pay.

Asgore apparently lives irresponsibly and is negligent towards himself. Excluding the flowers, Flower King's second floor is unkempt compared to the first floor. Paperwork is also scattered on that floor and in his truck.

Sans's Appearance: Sans appears as a relatively short and paunchy skeleton, with mitten-like hands. Sans is always seen with a wide, toothy-grin on his face. Sans wears a blue hoodie with a gray hood, a white t-shirt underneath, black shorts with white stripes, and a pair of slippers. He has white dots for pupils in his black eye sockets that disappear when he is serious or angered. When Sans uses telekinesis, his left eye flashes light blue and yellow (the colors for patience and justice) while his right pupil vanishes.

Sans's Personality: Sans appears to be a laid-back character, with his lowercase dialogue reflecting his personality. Sans enjoys messing around with others for his amusement. He also seems to be amiable towards Kris and eager to interact with the citizens of Hometown after moving in recently. It is notable that he deeply cares for the well-being of his younger brother Papyrus, Sans enjoys making jokes and puns, as shown when he interacted with Toriel in his store after she forgot the eggs she brought. Despite this, Sans is capable of sensing tension amongst others. When Asgore abruptly interrupts his and Toriel's conversation by cracking a pun at his own expense, he quickly turns his back on the two and doesn't turn around until Toriel leaves, likely not wanting any part in their divorce-driven dilemma. His conversation with Asgore afterwards is rather awkward as well, as when the latter asks what flower would remind Toriel of the time they first met, Sans' only response is that he should probably "talk to his plants about that."

Sans never expresses surprise or confusion. When Kris greets him as an old friend or asks for news about his brother Papyrus despite never having heard of him before, his only reaction is to wink at Kris.

He is also observant; Sans reads the people's expressions and can often tell when they have already done certain tasks, as when SAVING and reloading. Though Sans is usually agreeable, he can become eerily serious to emphasize a subject.

Sans may have a scientific background. Evidence includes the quantum physics book, his workshop, affinity for science, his inexplicable ability to teleport and his timeline research.

Sans has implied he once longed and searched for a life that he cannot go back to as he "gave up trying to go back a long time ago".

Alphys's Appearance: Alphys is a yellow lizard-like monster with buck teeth. She wears square glasses, a dark green jacket, a red tie, a light green shirt, and brown pants.

Alphys's Personality: Alphys is shy and often stutters when conversing. She occasionally makes self-deprecating jokes. Alphys appears to try her best in guiding her students to succeed. Alphys is implied to be a recluse, often eating instant ramen noodles in the dark when she is at home.

Alphys's interests include watching anime, primarily "Mew Mew Kissy Cutie 2" for its dark storyline and mature themes "The Symptons" sitcom series, video games, and reading superhero comics. It is suggested through her classroom's desktop wallpaper that she has an interest in muscular heroes. Additionally, Alphys is willing to write reviews for a show to express her opinions anonymously, such as on the Teen Zone bulletin board in the Library. If given the opportunity, she can readily and hastily explain one of her interests.

Undyne's Appearance: Undyne is an anthropomorphic thin, blue-skinned, fish-like monster with a long, red ponytail, gill-like appendages on the sides of her head, and jagged yellow teeth. She wears a navy blue police uniform, complete with navy blue tints. Unlike her counterpart in Undertale, who wears a black eyepatch over her left eye, Chief Undyne has both eyes fully intact.

In a Dark World, Undyne dons a silver-gray armor set similar to that of her Undertale counterpart with large shoulder pads, armored gauntlets, a star-shaped badge, and a police hat resembling the upper-half of a star crest. Her scales becomes a more vivid cyan and her hair gains bright, neon pink highlights.

Undyne's Personality: Undyne is hot-blooded and enthusiastic, and shows passion in everything she does, including things she does badly, such as singing. Her passionate nature leads her to overreact to minor incidents and she becomes easily bored with the low level of crime in Hometown, indicating that she would prefer to have some sort of action occur during the course of her duties. She eagerly looks forward to beating up any criminals or wrongdoers. Undyne is good at sports, and plays the piano.

Despite her tendency to overreact, Undyne is shown to take her duty as Hometown's police chief seriously. She demonstrates a strong grasp on assessing a situation when it matters, as shown when stopping the Knight from kidnapping Toriel. Even without fully understanding what's happening, Undyne doesn't let her confusion interfere with her job, acting decisively and with conviction.

Rudy's Appearance: Rudy is a monster who resembles a reindeer. He has tan fur, a deep voice, a narrow face, dark hair, and wears a thin mustache and goatee. In the Hospital, he wears a white sleeveless hospital gown.

Rudy's Personality: A jovial and lighthearted person, Rudy resembles Sans in his use of humor and jokes to lighten the mood, and is lively and talkative despite his medical condition. He is close with and protective of Noelle and likes playing video games with her. He is supportive of Noelle's desire to pursue her crush on Susie and lightheartedly threatens anyone who he sees as hurting or insulting her, as seen when he expresses a desire to throw something at Berdly, and says that he will "Kick Kris's ass" if they insult Noelle's singing in choir.

Carol's Appearance: Carol is a monster who resembles a reindeer. She has pale beige fur, light blonde hair and darker beige freckles. She has blue antlers, blue eyes, a blue nose and either blue lips or blue lipstick. Her work clothes appear to be a blue blazer, black trousers, black heels and a pearl necklace.

Carol's Personality: Carol has a very cold and icy demeanor, and is very firm in her words. Noelle is evidently intimidated by her harsh, authoritarian nature. In a conversation with him at the Hospital, Rudy mentions a desire to get out of the hospital so he can return home, worrying about Noelle's wellbeing with Carol being the only parental figure around. This further shows her coldness and distance from the family, as Rudy thinks Carol's usual terse mannerisms might genuinely pose a threat to Noelle's mental health.

It also seems that Carol is very protective of her home's belongings. When she discovers Susie playing Dess's guitar, she snatches it off her and angrily kicks her out of the house, ordering her to never talk to Noelle again. Her protectiveness of her home's belongings is likely an act of larger preservation, as stated by Rudy in the Church. He cites a story where Noelle made snowflake cutouts for her to bring to work; Carol instead decides to keep them at home, likely not wanting harm to befall them in a less curated environment, even if it made a younger Noelle cry.

As the Mayor, Carol is efficient and diligent, though she is not charismatic. According to Asgore, however, she shows a nicer side once she has warmed up to someone. She displays a surprisingly hospitable attitude towards Kris (or quite possibly their SOUL), in stark contrast to her hostile treatment of Susie she also the Mayor of Hometown. Due to her diligent efforts, there is no crime in Hometown, and she is unopposed.

Gerson's Appearance: Gerson Boom, as a Darkner, is an elderly dark-green tortoise with a dark green spot on the left side of his head. He has has a yellow sclera and a black pupil, and he seems to be unable to open his right eye. He has pink hair, much like his son, as opposed to having olive-green skin and gray hair as seen in Undertale. Gerson's long pink eyebrow and pointed goatee are usually visible, though he has a long pink flowing ponytail hidden underneath his cap. The back of his shell is dark brown. Gerson sports a brown flat cap, blazer, and trousers. He wears loosely-hanging light brown scarf around his neck, and has a white undershirt. Gerson occasionally walks with a green walking stick.

As Hammer of Justice, Gerson swaps his typical brown suit for silver body armor and armored boots, and forgoes his green cane for a giant hammer. No longer wearing his hat, Gerson lets his long pink hair flow out.

Gerson's Personality: Father Alvin perceives Gerson as a "brave man, brilliant, and sharp" as mentioned in Chapter 2. The writing for the Memorial Bench implies that Gerson was welcoming, supportive, and encouraging when it involves finding inspiration. Simultaneously, it also implies he was open-minded to new and abstract ideas, as he was inspired by his dreams. Gerson is implied to be somewhat laid-back as a teacher, as he was willing to compensate for tardy students, allowing them to bring him leftover crepes from QC's Diner.

Gerson's interactions with Susie also reflect on what he was like as a teacher, with Alvin implying that he was great at his job. He looks for his pupils' strengths and tries to uplift them in his lessons, never talking down to them. His feigning of "old man" stereotypes also plays a part in this, such as him tricking Susie into healing Jackenstein by dropping his letter and leaning to pick it up when he asks her to heal him.

In battle, Gerson demonstrates a great spryness and battle-readiness for his old age, constantly kicking his legs out in place while carrying his massive war hammer behind his back in his idle animation, and demonstrating great speed in his many attack animations. He displays a level of confidence and cockiness throughout the fight, posing in a one-handed handstand as he dodges attacks, and boisterously laughing after his fakeout final strike at the end of his final attack sequence.

Both the mid-battle text and the stars that appear above his head signal his delight when Susie does something to impress him, mainly by attacking him or by using healing magic. This is mirrored in gameplay by tying Susie's attacks and heals to the progression of battle; the fight takes longer if Susie never attacks or heals. Gerson also progressively deals less damage to Susie the lower her health is; this suggests that Gerson is not interested in winning outright.

Lancer's Appearance: Lancer is a short and chubby black, blue, and white Darkner with a teardrop-shaped head and blue spade symbol on his body. The upper half of his face is hidden by a large, spade-shaped shadow. He has a large mouth and a prominent blue tongue that he usually sticks out.

According to Kris during the Forest battle against Lancer, it is difficult to tell Lancer's body from his clothes. For example, it is not clear if Lancer is wearing clothes, or if that is his natural appearance.

Lancer's sprite appears to be less detailed than the other characters, and does not have a walking animation, so he slides along the ground when moving.

In the Light World, Lancer is a Jack of Spades card, although his in-game appearance is simply a blank card with a spade symbol in the middle, resembling an ace.

Lancer's Personality: Lancer is very childish and generally immature in his behavior and speech. He delivers his lines with a near-constant smile on his face. He is easily preoccupied with childish games and pursuits and likes hiding things and irritating people. He generally assumes that the party naively follows instructions on signs he writes. He has a poor sense of direction and gets lost in mazes quite easily. He can be easily intimidated by strong enemies like K. Round, although he remains calm and jovial while doing so.

Lancer values and idolizes his father, King. He tries to project a tough facade in imitation of him, hoping to be designated "son of the month," and caring for his father's well-being and approval despite being neglected. Aware that his father's subjects don't like him and only put up with him due to King's orders, he seeks real friendship and gradually becomes an ally to the party despite his initially hostile role.

Lancer seems to have unusual eating habits. Rouxls Kaard claims that whenever King forgets to feed his son, Lancer cries like a baby bird until Rouxls feeds him worms. Furthermore, using the "Anything" ACT on him on his second fight may involve Kris attempting to stop the fight by offering him a picnic basket of worms, to which Lancer reacts with enthusiasm. Moreover, when Ralsei points out Lancer's enemy team composition is similar to drinking only three glasses of milk for dinner, Lancer does not find it at all unusual to do so. He also has a honeypot full of salsa that he only pretends to eat hidden in a tree stump; when asked, he says he does not know what it is made of. More salsa is stored in a hole he dug in his room.

Rouxls's Appearance: Rouxls Kaard is an adult-sized humanoid. His head is diamond-shaped, with long white hair parted to his left, and a face with a slightly melted appearance composed of two diamond-shaped eyes and a large mouth, which appears to be overlapped by a vertical strip of skin. He wears a royal blue suit with epaulets. In terms of color-scheme, Rouxls is a flashy deep blue except when in his shop, where he appears black.

Rouxls's Personality: Rouxls acts very egotistically during the events of Chapter 1. He claims to be the Duke of Puzzles, and attempts to stop the party by forcing them to solve his puzzles. However, he is an incompetent puzzle-maker: each of his puzzles consist of the bare minimum of elements — a box and a button — and he makes no attempt to obfuscate the solution in any way. He also vandalizes clues on puzzles he did not create, in order to make them "harder."

He attempts to use Early Modern English speech patterns, presumably to appear educated, but it is highly stereotyped. Commonly, Rouxls replaces most instances of "you" with "thou," randomly adds "-est" and "-eth" suffixes that normally appear with "thou" conjugation, needlessly adds silent "e's" to the end of random words (thus implying wrongly lengthened vowels), and haphazardly capitalizes phrases for emphasis. When his pride is hurt, he doubles down by intensifying his misuse of Early Modern English to the point of incomprehensibility; but when surprised or stressed, he tends to drop it altogether. Swatch insults Rouxls's pronunciation, stating "he stole our flower display for one of his 'boo-kettes'," implying a mispronunciation of the French-origin "bouquet."

Rouxls is the shopkeeper on the fifth floor of Card Castle; initially, he says that he's merely selling the heroes items in order to raise money to defeat them. After all his puzzles are solved and K. Round is defeated, however, he proclaims he is now their ally as he is "always on the winning side," indicating a lack of loyalty in his character. After the downfall of King, he starts searching for a new tyrant to work under.

As shown by his short-lived relationship with Lanino and Elnina, he is bisexual and polyamorous.

Lancer considers Rouxls to be his "lesser dad." Rouxls is alternately irritated with and endeared by Lancer and his antics.

King's Appearance: King shares multiple features with his son, such as a portly body, the teardrop-shaped head with a black spade where his eyes should be, a mouth showing his tongue and big teeth, a broad and white/dark grey body, and blue gloves and boots. What differentiates him from Lancer is the three-spiked crown on his head, the enormous mouth (with more square shaped teeth compared to the curved fang shaped ones in the mouth on his face) on his large stomach shaped like a blue spade from where a chain comes out when used as a weapon in battle, and the black cape that flies away at the end of the battle. King's right arm can also be seen when he turns around or is carried by the crowd at the end of his battle, and also during some of his attacks.

King's Personality: King is a cold-hearted Darkner who has little compassion for his subjects and only considers his own wishes. He is also power-hungry, as evidenced by his desire to gain control over both the Dark and Light Worlds, along with his allegiance to the Knight. He resents Lightners, believing them to have abandoned Darkners, and is convinced that opening Dark Fountains will bring glory to Darkners.

King is initially shown to be somewhat abusive towards his son, Lancer; he speaks harshly to him, uses him as a hostage to gain the upper hand in the battle against the party and even threatens to kill him if Kris, Ralsei, and Susie do not surrender. Later on, it is revealed that King does care about his son to an extent. When talking to him in his cell, he asks if Lancer was happy and dismisses his intentions of throwing him off Card Castle's roof as a bluff, noting that Lancer would just bounce off even if he did drop him and calling him a "bouncy little pumpkin." He also has a fun time with his son watching Tenna perform for them, complimenting him on his choice of the new court jester. However, he is still quite strict with Lancer, forbidding him from eating Dark Candy - likely because it is bad for his teeth - and from saying "tier-two swear words", having him take a shower every time he so much as reads one.

Jevil's Appearance: Jevil is a short, pudgy imp with a round gray face, elven ears, clown-like eyes with small yellow pupils and black sclerae, and a large smiling mouth with yellow, sharp teeth. He has a long, purple tongue which can be seen either when he laughs, or during some of his attacks. He has a purple tail shaped like a capital letter J. He is dressed in a purple shirt, black trousers, a black cape, green slippers, black socks, purple mittens, and a lime green and yellow jester's collar. He wears a purple and black harlequin jester hat with two small yellow bells. His head appears to be connected to his body via a coil spring (akin to that found in a jack-in-the-box), which is only exposed when attacked.

Jevil's Personality: Jevil is described as mad since he met a "strange someone." Prior to losing his mind, he was a jester with a presumed humorous attitude and a friend of Seam.

Now insane, Jevil is still portrayed as an eccentric individual. His dialogue is rife with maniacal laughter, repeated words, rambling puns, and strange sentences, and he has a sadistic sense of entertainment, considering battle with the party to be a "GAME." He has a very cynical view of the world around him and considers everyone around him to be trapped while he is the only one truly free, despite ironically being jailed from the world. Seam, however, finds some sense in the words of Jevil, indicating that his insanity might be a form of awareness.

Jevil, like other Card Kingdom denizens, is implied to be a playing card. Specifically, he is implied to be the Joker, as he was the court jester. This is also evidenced by how he claims that he can do anything, as the Joker's most frequent use is a wild card.

Queen's Appearance: Queen is a tall and slim black, azure, and white Darkner. She wears a sleeveless black top with an azure masonic collar that has slightly spiked shoulders and a large white medici-styled collar, white pants/leggings (occasionally with either side half of the pants being shaded azure), black high-heeled calf-length boots, elbow-length azure gloves, a beauty spot at the right of her eyes, azure lipstick, and an azure cap with black marks on each side that sweeps significantly behind her head. Her eyes are a dark screen with a heart-like shape with eyelashes , occasionally showing red text according to her emotions.

GIGA Queen (that is her titan mech) has white skin like Queen, along with a black heart-shaped screen as eyes, while having a jordy-blue star-like cap, and matching lipstick. She wears azure shoulder pads, a sleeveless jordy-blue leotard with a thin black belt around it that has a azure diamond-shaped crystal-like object in the middle of her, shorter azure gloves, and azure high-heeled pumps. When doing her acid attack, GIGA Queen's star cap and leotard turn to the same green color as her acid.

Queen's Personality: Queen is a benevolent, if somewhat airheaded, person. While she is the main antagonist, it is mostly out of lack of insight rather than malice. She seems reluctant about controlling people she likes, and would rather they willingly go along with her plans to make them happy. She is also prone to giving people pet names and describing them using fun adjectives. She genuinely believes she is doing the right thing by opening Dark Fountains, and after she learns the truth of The Roaring from Ralsei, she recognizes that she was misguided and immediately stops her plan.

Spamton's Appearance: Spamton is a diminutive ex-Addison with a large head and short limbs. Similar to the Addisons, his colors consist of the default color palettes in Microsoft Paint.

Spamton has black hair that is slicked back, appearing similar to a pompadour, an elongated nose, red cheeks, and white skin. Spamton wears black-framed glasses with colored lens. Spamton's right lens is pink, and his left is yellow. However, it can fluctuate between the aforementioned colors. Sometimes, his black pupils are visible. Rarely, Spamton's lens can be replaced with video noise effects, with the occasional blue tears. Spamton has the ability to increase the size of his head. Additionally, his face seemingly glitches sporadically. For his attire, Spamton wears a long-sleeved black V-neck shirt, and nondescript white pants and shoes.

Spamton's design seems to be based on a number of popular depictions of puppets, having the face and style of dress seen on classic ventriloquist dummies with a (nonlengthening) nose similar to Pinocchio's. This is also hinted at in his Spamton NEO form when he refers to himself as a puppet, and with the song A Real Boy.

As Spamton NEO, Spamton assumes the form of the machine he inhabits. His head is larger than normal, and his glasses have their colors swapped, with his right lens being yellow, and his left being pink.

The body resembles a disheveled version of Undertale's Mettaton NEO, with his right hand being able to change into a yellow and magenta laser cannon, and black torso with long white boots. In contrast, the magenta chest piece has a yellow and pink triangle, his arms have magenta bracers.

The wings still have pointed ends, but are instead static. One wing has a grey thumb, and a purple base accented with lilac and green, and the other wing has a teal-green thumb, and a magenta base with pink and yellow accents. His torso armor and wings seem to make up the shape of the Delta Rune.

Above Spamton NEO, countless green wires suspend him in the air. His limbs and wings also loosely hang.

Spamton's Personality: Spamton was once a natural salesman, always willing to cut a deal. While he still bears a shadow of these traits, his deals are now often nonsensical or violent. He claims that he became a salesman not for the money, but for the freedom to make his own deals. However, he still attempts to scam Kris for money (which he refers to as "Kromer") at every opportunity. His speech patterns are similar to typical obfuscated spam email text, with many words replaced with non sequitur variants in square brackets that could imply incorrectly-applied mail merge variables or hyperlinks, or various voice glitches.

In much of his dialogue, he seems desperate and mentally unwell, seemingly projecting himself onto Kris, contradicting himself, and saying things which make little sense, without warning. This mental instability seems to clear up briefly after fighting him in his NEO form, as he wishes Kris success with their journey without using broken English.

Spamton consistently spells "generosity" as "genorisity," "guarantee" as "guaranttee," "delicious" as "delisis," and "special" as "specil," with an exception for the latter at the end of the Spamton NEO battle after snapping all the wires.

Tenna's Appearance: Tenna is a humanoid Darkner with no eyes and a long nose, having a cuboid television for a head, similar in appearance to the television of the Dreemurr Residence he is based off of. Tenna wears a white shirt and yellow tie underneath a red tailcoat with the letters "TV" attached to his left coat breast in gold. He wears black pants, held by a TV-shaped golden belt, alongside long yellow shoes with black soles and white gloves.

Tenna's nose sometimes disappears on its own when his screen goes blank. His nose is detachable, with one of the descriptions of TV Dinner mentioning his nose is used as the ice cream cone. According to Small Mike, he has a "nose drawer" that the Mikes have to organize.

Normally, Tenna is quite large, being more than twice as tall as Susie. However, he shrinks in size whenever he feels down. Unlike other characters, his sprites are taken from a prerendered 3D model.

Tenna's Personality: Tenna's personality is that of a typical TV announcer — high-energy, excitable, and always quick with a joke. He regularly uses detailed text graphics in his dialogue, with each graphic being accompanied by a sound effect. However, it is revealed that beneath Tenna's jubilant exterior, he is deeply insecure and afraid of being abandoned and useless. This is demonstrated when he starts mentally breaking down whilst trying to keep Kris, Susie, and Ralsei from leaving his Dark World by trapping them in gachapon bubbles. His primary motivation is to entertain Lightners. As the Dreemurr family no longer watches TV, the long time since he has last been used leaves Tenna lonely and increasingly desperate to hold onto the party when they stumble into his Dark World.

It is repeatedly insinuated that Tenna is a bad boss to the other Darkners of TV Time, as he has them all in iron-clad contracts that allow him to control their wages, forcing them to do whatever he wants. However, the Darkners of the TV World have a small bit of freedom, allowing them to quit the contract.

Knight's Appearance: The Knight is a tall and sharp pitch-black silhouette with a white outline. Its helm is diamond-shaped, with its opening resembling the visor of a frog-mouth helm, which can interchangeably shift to act as either a visor or a mouth in its animations. At the sides of the helm are two long protrusions, which resemble three-pointed sharp horns or antlers.

Its body is slim and angular, with large triangular pauldrons, a thin waist, and pointy legs with no discernible feet. Each hand appears to have a large hole through the palm, or alternatively eyes, akin to the Titans.

The Knight's body can change to significant degrees: its helm's opening can morph and shift around its face, and can have sharp, visible fangs. When roaring, its head becomes more monstrous, having eyes and a mouth simultaneously, and its chest opens up with a large eye in the center. It can quickly collapse into a small ball to dodge attacks, or transform into an avian creature. When taking enough damage, its body becomes rough and spiky like static.

Knight's Personality: Little is known of the Knight's personality, as it rarely appears in person; when it does in Chapters 3 and 4, it never speaks. While its motives are unknown, it is shown to be ruthlessly aggressive towards its enemies and even its servants when disappointed by them, as evidenced when it attacked Tenna the moment he released Toriel from her gachapon prison. It often screams, whether it's in fury, triumph, agony, or simply as a taunt.

Occasionally, there are moments in which the Knight displays arrogance, such as when Susie chases it up a staircase and the Knight simply drifts away with its arms crossed. Another example is seen when it starts laughing in response to Susie’s statement that once the last fountain is sealed, it will be over for them.

After defeating Tenna and right before trying to grab Toriel in front of Kris' and the others' eyes, the Knight is shown to have a hard-to-decipher animation where it slouches down, dripping some sort of liquid, as its "eye" turns black. Whether this action corresponds to crying, drooling, or something else is uncertain.

Despite the Knight's violent and ruthless demeanor, it seems to be more tolerant of Kris. The Knight simply "DOWNs" Kris during their fight in Chapter 3, instead of causing them to "SWOON" like the other party members. Should the party survive this fight long enough, the Knight brutally strikes down Susie and Ralsei in a cutscene, leaving Kris the last to stand. The Knight then slowly places its sword on Kris's shoulder, mimicking the act of knighting, before the scene cuts to Kris in their DOWNed pose.

Titan's Appearance: While it initially resembles a Dark Fountain, the geyser quickly hardens into a stone pillar and cracks open like an egg, revealing its true form.

In this form, its body is black and covered in eyes, and it has clawed, human-like hands covered in eyes, along with large white wings. At the top of its body is a faceless, winged, humanoid head with a hole in place of a face (normally covered by a shield that resembles a SAVE Point). The head is the only part of its body that's visible when the party fights it.

The Titan's description and appearance may imply that this form is unique to this Titan, and that other Titans may take on different forms based on the Dark World they are created in.

Titan's Personality: According to what Ralsei states about the Titans before the battle, the Titan has no cognition or personality to speak of. He claims it only exists for the purpose of destroying everything in sight, generating Titan Spawn to help it do so. Upon attempting to SPARE it, the narration states that the Titan is "not something that can understand MERCY."

The Titan does not speak during its battle. It appears to have some amount of instinctive ability to recognize threats to its survival, as when it is damaged, it withdraws its head behind its wings to absorb its Spawn to heal. Beyond that, it does not seem to care for its offspring at all, as besides absorbing them, it will carelessly destroy them with its attacks while its shield is broken in an attempt to attack the SOUL.
